` Application filed August 4, 1922. Serial N0. 579,719.

7'0 all w/Lomt may cancer/m:

citizen of the United o States, residing at Cincinnati, in the county ofHamilton and State of 'Ohio, have invented certain new and usefulImprovenents in Switch Stands, of which the followingl is aspecification.

My invention relates to means for throwing the switch points into openor closed position.

rl`he object ofmy invention is to provide simple, convenient,el'ficient, economica-l and easily operated means for operating theswitch stand in a confined space to' throw the switch points into eitheropen or closed position. V

My invention consists in providing a base having the switch throwinglever pivotally mounted thereon to be inoved parallel with the track andalso having a bell crank pivotally nounted on said base with one armsuitably connected to the switch throwing lever near the pivoted endthereof and having the other arm of said bell crank pivotally connectedto a connecting rod suitably attached to the switch points.

My invention also consists in the constructionl combination andarrangement of parts as herein set forth and claimed.

In the drawings: i

Fig. 1 is a plan view of my invention;

Fin. 2 is a perspective view of the switch stand and solid connectingrod;

Fin: 3 is a side elevation of Fig. 1;

Fi. 4 is a perspective view of the switch stand showing a modified formof connecting rod to permit the switch to be run through in onedirection and automatically return the switch points to closed position.

In the embodiment of iny invention as illustrated and which shows apreferred construction, provide an ofl'set base 1 having end 2 thereofparallel with end 3. Each end is provided with suitableyspike openings11 by which the base maybe securely fastened to the cross ties. End 2 isprovided with a transverse bearing 5 on the upper side thereof and hasjournal 6 of switch throwing lever 7 pivotally mounted therein and heldin place by a. Spring cotter 8. End 3 of said base is provided with abearingV boss 9'having a: cylindrical stud 10 extending upwardlythere-from on which a 'bell crank 11 is mounted.

A pitman 12 is pivotally connected at plc, easy and efiicient.

v one end to arm 13 ofl saidbell cra'nk and le it known that'I, GEORGEASHTON, a

is'pivotally connected at its other endto said; switch throwing level-ata point nearv` its pivotal. connection. Connectin rod 14 is connected atoneyend to the switch points and at the other end to arin 15 of saidbell Crank. In Fig. 4 I have shown a modified Construction of connectingrod 14 which is adapted to permit a train-to run through the switch inone direction and to auto- Inatically return saidA switch points intoclosed position. against the main rail.

The operation of the switch is very sini- To close the switch nerelythrow the lever 7 from the position illustrated in Figs. 1, 2, 3 and 4until it assuineszthe position indicated by dotted lines in Fig. 1. Thismovement of the switch .throwing lever will operate the connecting rodthrough the bell cra-nk and pitman to move the switch points.

It will be seen that this Construction and arrangement may be inountedin a Vvery narrow space upon the cross ties at one side of the track andpermit the switch throwing lever to be thrown parallel with the trackinstead of transversely thereof, thus permitting the operation of theswitch stand in a very contracted or narrow space such as in a tunnel.

lVhile I have shown and described a particular Construction andarrangement of parts, it will be understood that various modificationsthereof may be made without departinglfroin the scopeV or spirit of theinvention as defined in the claims.

VVhat I c-laim as new and desire to secure -by Letters Patent is:

1. A switch stand comprisng a base having a horizontal bearing at oneend and a vertical stud at the other end thereof, a switch throwinglever mounted in said horizontal hearing,- and having a weight thereon,adapted when in downwardly closed position to be entirely removedvertically from said base7 a bell crank mounted on said stud and abovesaid base and having the outer end of one arm entirely removedvertically from said base and having its other arm extendingin parallelrelation and above said base, a pitman having one end pivotallygconnected to said switch throwing lever adjacent said horizontal bearingand having,` its other end pivotally connected to one arm of said bellcrank, and

a switch throwing oonnecting rod pivota-lly one end and a. vertical studat the other-end thereof, a switch throvvng lever monnted in saidhorizontal bearing and having a Weight thereon adapted When in downwardposition kto be entirely removed from said base, a bell crank nounted"on said .stnd and having one arn entirely removed vertially connected tosaid switch throwing lever adjacent said horizontal bearing and havingits other end pivotally connected to one arn of said bell Crank, aswitch throwinr 'connectingrod pivotally connected to the other arm ofsaid bell Crank, and a yeldable means connected to said connecting rodadjacent said switch stand.

GEORGE ASHTON.
